' citizen of the United States, residing ing clogged by an accumulation of weeds Utica, in the county of La Salle and State of Illinois, have inventedcertain new and useful Improvements in Attachments for Cultivators, of which the following' is aspecification.

This invention is an attachment'for culA ti vators having for its object the prevention of the scrapers or cult vator blades becomand vines. Specifically stated, the invention seeks to provide a simple and inexpensive mechanism which may be readily mounted upon acultivator' frame and which will include a cutter disposed adj acent the cultivator blades whereby vines, weeds and similar growth raised from thesu'stace of the ground by the cultivator blades will be cut through and thereby prevented from c linging to and clogging the'action of the cultivator. The invention seeks further to provide means whereby the said cutterwill be rotated positively as the cultivator is drawn over afield sothat the weeds and vines will be positively severed. These stated objects and other objects which will incidentally appear in the course of the following description are attained in such a mechanism as is illustrated in the accompanying drawings, and the invention resides in certain novel features which will be particu larly pointed out in the claims following the; description.

In the drawings:

transversely in rearwardly projecting lugs or cars 7 of the block are hangers 8 in the rear ends of which is mounted an axle 9 carrying a wheel or roller 10 which is adapted to run upon the ground and actuate the said axle 9-Vwhich carries a sprocket wheel 11. A chain 12 is trained around the saidv sprocket 11 and a sprocket 13 on the shaftG whereby the said shaft is rotated as the machine is drawn over the ffield. :The hangers 8 are preferably extensible as will be readily understood, so that the proper tension may be maintained upon the chain 12 and in the drawings-the said hangers are shown as consistingof two sections slid ably connected by a ringor collar 14 and secured in an adjusted position by a bolt 15 and a suitable nut mounted thereon. A pin or rod 16 rises from the axle 9 and plays in the, rear free end of the beam 5, as shown,

a spring 17 being coiledaroun'd the rod be-' tween the said beam and the axle so that the roller or wheel 10 will, be held yieldably to the ground and caused to positively drive the gearing but may readily ride over stones and other obstructions." On the end of the shaft 6' remote from the sprocket 18, I- secure a beveled pinion 18 which meshes with a gear 19 on the'lower end of a vertical shaft 20 which is journaled in the block 4%, as shown. Upon'the upper end of this shaft 20, 1 Secure a sprocket pinion 21 and a chain 22 is trained around the said pinion and around other pinions at the heads of the cutter supports to actuate the gearing by which the cutters are'rOtatedQ a v As shown clearly in Figs. 1 and 3, the bracket 2 projects forwardly and at both sides of the arch 3 orothermember of the cultivator frame. In the ends of the said bracket, 1 secure posts or standards23 to the lower ends of which the scrapers or cultivator blades 24 are secured by a bolt 25 passing through an enlargement of the standard and through a lug 26 on the blade. The leg or standard 23 is vertically slotted, as shown at 27 and also has a vertical bore 28 formed therethrough, the said bore opening through the upper end of the post and terminating at its lower end in'a cavity or opening 29 formed in the post, as clearly shown in Fig. 6. A vertical shaft 30 is rotatably fitted in the bore 28 and has its upper end extended above the bracket 2, as clearly shown, and equipped with a sprocket Wheel 31 around which the chain 22 is trained. To the lower end of the said shaft 30, I secure a beveled pinion 32 which meshes with a similar pinion 33 on a transverse shaft 34 which passes through the chamber 29 in the post and also through the slot 27 therein, being journaled in that portion of the post constituting the outer wall of the slot 27 and also in a plate or cap 35 covering the outer open end of the chamber 29 as will be readily understood. A cutting disk 36 is secured upon the shaft 34 within the slot 27 and will be positivelv rotated whea the described mechanism is set in motion.

To maintain the proper tension upon the chain 22, I secure upon the blocks a laterally extending arm 37 having an idler sprocket 38 mounted upon its inner end and provided with a longitudinal slot 39 at its outer end through which a bolt 40 is inserted into the block a whereby the said arm may be adjusted so that the engagement of the sprocket 38 with the chain 32 will maintain the chain under proper tension.

It will be readily understood from the.

foregoing description and upon reference to Figs. 5 and 6 that the cutting disk 36is located just above the scraper or cultivator blade 25 so that itmay readily act upon the vines and weeds turned up by the scraper and, to positively direct the said vegetation to the cutter, deflecting plates 41-1 are secured to the lower end of the post 23 at opposite sides of the cutter and have their forward edges inclined upwardly and rearwardly from the cultivator blade 24 so that the forward travel of the machine will force the weeds and other plants up against the edge' of the cutting disk as will be readily understood.

As. machine is drawn over the field, the rolle o; i0 will be rotated by reason .nent with the surface of the axle 9 thereby directly set in than of the axle 9 will be 1,4011 ,soa

caused to rotate and cut through the vines and stems forced against it by the forward travel of the machine.

it will. thus be seen that l have provided a very simple, efficient and direct acting weed cutter which maybe readily applied to any form of cultivator or wheeled plow without material change in the construction of any of the parts. My device will not interfere with the usual operation of the cultivator but will facilitate that operation by preventing choking of the cultivator blades and will not add materially to the draft of the machine. f r- Having thus described the invention, what is claimed as new is: y

1. The combination with a cultivator frame, of a post secured thereon, a cultivator blade carried by the lower end of said post, a rotary cutter mounted on said post adjacent and above the blade, deflecting plates secured to the post to direct vines'from the blade to the cutter, and means support-edon the cultivator frame for said cutter.

2. The combination with ,a cultivator frame, of a post secured thereon, a rotary cutter carried by the post, a shaftlmounted vertically in the post, gearing connectlng said shaft with the cutter, and means carried by the cultivator frame for rotating said shaft. 3. The combination with a cultivator frame, of a post secured thereon, ,a rotary cutter carried by the post, a shaft disposed vertically within the postand operatively connected with said cutter, a sprocket secured on the upper end of the said shaft, a second sprocket carried by the cultivator frame in rear of the first-mentioned sprocket, a chain trained around said sprockets, and means carried by the cultivator frame for positively actuating the second-mentioned sprocket.

4. The combination with frame, of brackets secured thereto, a post mounted in one of-said brackets at theforward end thereof, a rotatable-cutter carried by said post, a shaft mounted vertically in the post and operatively connected with said cutter, a sprocket on the upper end of. said shaft, a shaft mounted vertically in the rearcend of one of the brackets, a sprocket on the upper end of said shaft operatively connected with the first mentioned sprocket, a gear on the lower end of said last-mentioned vertically disposed shaft, ahorizontal shaft in said bracket below saidgeana gear on said horizontal shaft meshing with the first-mentioned gear, and means actuated by the travel of the'cultivator for rotating said horizontal shaft. z

5. The combination with a cultivator,

positively actuating a cultivator cultivator frame in advance of said beam, a

rotary cutter carried by said post, a vertical shaft housed in said post and operatively connected with said cutter, hangers disposed below the beam and extending downwardly and rearwardly, an axle carried by the rear ends of said hangers, a ground wheel fixed upon said axle, yieldable means disposed between the beam and the axle for holding the said wheel to the ground, and gearing 1o actuated by said axle and connecting the same with the vertically disposed shaft in the post.

In testimony whereof I affix my signature.
